^ That. I can hit 17psi in 1st gear with my GrimmSpeed 3-port BCS. Like I mentioned before, if you have a boost leak somewhere you won't go past waste gate pressure. You should really do a boost leak test. You could test the waste gate functionality by looping the waste gate line to the turbo compressor outlet BUT DO NOT GOOSE IT because it will stay closed. This is only to test that you can go above waste gate pressure and the waste gate isn't stuck open.
